Problems solved by technology

[0003] At present, most browsers are mostly based on applications on personal computers or mobile phones, so that their core parsing engines cannot be well applied to digital TV interactive service tag language. The support is incomplete, and most of these engines take up a lot of computer resources, which is not suitable for the feature of less embedded resources. Therefore, it is particularly important to design and implement a tag language analysis that can support digital TV interactive services.

Abstract

The embodiment of the invention discloses a digital television interaction service tag language resolution method, which comprises the following steps of: acquiring network resource information; identifying tag information in the network resource information, resolving the acquired network resource information into a tag stream, and tagging special tags belonging to a digital television interaction tag language; constructing a document object model (DOM) tree for the digital television interaction tag language; and constructing a Render tree on the constructed DOM tree, realizing the rendering of web pages and adding node position coordinates and color typesetting information. The embodiment of the invention also discloses a digital television interaction service tag language resolution system. In the method and the system, the digital television interaction service tag language can be more comprehensively supported and the rendering of the web pages can be more rapidly realized.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method and system for analyzing the label language of a digital television interactive service. Background technique [0002] Digital TV interactive service tag language is the main content of digital TV interactive service for function extraction and abstraction, and based on the current popular XML language to expand, fully considering the performance and function of terminal receiving equipment (set-top boxes, all-in-one machines, etc.) environment and Tolerance, form a complete set of terminal-oriented content description language, and finally form the standard specification of terminal-oriented content description language, so that interactive service developers can customize flexible presentation pages and interactive processes according to the different interactive service content provided, Interpretation, presentation and data interaction are performed throug...
